Erroneous billing and tempering with my credit profile

It has been 7 days since my last review about VODACOM and my request to the to send me a written letter confirming that I do not owe them. They told me a letter of confirmation that the ***** account has been deleted will be sent to me in 48 hours. That was last week Thursday. I am still waiting. I have been in constant telephonic contact with them everyday since and everyday I speak to a new person telling me that they have logged my request.

On Tuesday, VODACOM sent me an sms saying that they have corrected my credit rating and they said that they will send me a letter. However, still they have not sent me that letter which I urgently need because I have app**** for credit but, I was declined due to VODACOM saying I owe them when I dont.

So today, I have sent my formal complaint to the Credit Ombudsman as well as the National Consumer Commission reporting VODACOM for ruining my life.
